I have a Synology that needs more storage. Thoughts on WD vs Seagate?
I’ve always bought WD Red, but with the recent WD controversies (including the SMR/CMR scandal and the recent WDDA warning), I’m considering Seagate. Also, I can’t find any difference between the IronWolf Pro and Exos drives. What am I missing?
| Metric | Seagate IronWolf Pro 20TB | Seagate Exos X20 20TB | WD Red Pro 20TB |
|---|---|---|---|
| Spindle speed (RPM) | 7200 | 7200 | 7200 |
| Internal transfer rate | 285 MB/s | 272 MB/s | 268 MB/s |
| Gas | Helium | Helium | ??? |
| Cache | 256MB | 256MB | 512MB |
| CMR? | Yes | Yes | Yes |
| MTBF (hours) | 2.5m | 2.5m | 2.5m |
| Non-recoverable errors per bits read | 1 in 10^15 | 1 in 10^15 | 1 in 10^15 |
| Load unload cycles | 600k | 600k | 600k |
| Workload rate (TB/yr) | 550 | 550 | 550 |
| Annualized Failure Rate (AFR) | 0.35% | 0.35% | ??? |
| Warranty | 5yr | 5yr | 5yr |
| Price | $349.99 | $329.99 | $379.99 |
Also, please don’t recommend shucking (those drives are in external enclosures because they didn’t pass QC to become internal HDDs).
Exos are noisy, but they work great…
And the helium fill? Makes them sound funny
